During the equinox, the sun is directly over the equator, resulting in equal lengths of day and night. This balanced distribution of sunlight leads to more consistent heating and cooling of the Earth's surface, which helps regulate temperatures and create mild weather conditions.
Between the vernal equinox and the autumnal equinox, more than half of the hemisphere is illuminated by the sun, peaking at 63% illumination on the summer solstice. Likewise, between the autumnal equinox and the vernal equinox, less than half of the hemisphere is illuminated by the sun, reaching the minimum of 37% illumination on the winter solstice. As the Earth rotates, you are rotating through more sunlight and less darkness during the spring and summer months, and you are rotating through more darkness and less sunlight during the fall and winter months. Since the speed at which the Earth rotates is constant, you are spending more time in the sunlight in the spring and summer and more time in the darkness in the fall and winter.
The impact behavior of mild steel is significantly influenced by temperature. At lower temperatures, mild steel becomes more brittle, increasing the likelihood of fracture upon impact. Conversely, at higher temperatures, the steel exhibits improved ductility and toughness, allowing it to absorb more energy before failure. This temperature dependence is crucial in applications where materials are exposed to varying environmental conditions.
The Sun doesn't do anything at such. The Autumnal equinox is more down to the position of the Earth on its orbit of the Sun. The sun is directly over the equator and the amount of daylight and darkness is about equal around the world.
The idea that brooms can stand by themselves during the equinox is a myth and part of a fun folklore that suggests that the gravitational pull during this time makes it easier for them to balance. This belief is more about the novelty of the equinox than a scientific fact. The equinox occurs when day and night are approximately equal in length, which happens around March 20 or 21. However, some people may start celebrating or engaging with the idea a bit earlier, leading to the perception that it's "already starting."
As far as is known, there are none. It's true that people's mood is often improving and they're becoming generally more optimistic and horny at that time of year. But those are the effects of the increasing length of daylight, which begins with the previous solstice, and have no direct connection with the equinox.
At the vernal equinox, the Earth's tilt causes the sun to be directly above the equator, leading to more uniform heating of the Earth's surface. This uniform heating results in less temperature variation between regions, which in turn creates pressure differences that cause wind to blow from regions of high pressure to low pressure.

On a cloudy night, the general air temperature tends to be warmer compared to a clear night. The cloud cover acts as an insulating layer, trapping heat radiating from the Earth's surface. This results in reduced temperature drops during the night, often leading to a more mild and stable atmosphere. Consequently, cloudy nights are typically associated with less temperature variation and a more comfortable feel compared to their clear counterparts.
The full moon occurring nearest to the autumnal equinox is known as the Harvest Moon. It is characterized by its bright orange hue and historically helped farmers gather their crops late into the night. The proximity to the equinox results in a shorter time gap between sunset and moonrise, providing more natural light during the evening.
Echidnas in northern Australia are nocturnal. On occasion, they are seen during the day when the weather is mild. Echidnas in southern Australia tend to be more active during the day, especially during winter.
